THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 225,867, dated March23, 1880.

Application filed January 30, 1880.

To all whom it may concern Be it known that I, SAMUEL M. RHOADS, ofJeffersonville, in the county of Montgomery and State of Pennsylvania,have invented a new and Improved Shaft or Pole Oouplin g, of which thefollowing is a specification.

Figure l is a sectional side elevation with the shaft attached. Fig. 2is a sectional front elevation of the coupling on line as .r, Fig. 1.Fig. 3 is a plan view, showing the method of securing the thumb-screwstrap to the under side of the shaft or pole. Fig. 4 is a plan of thecover of the coupling. Fig. 5 is a perspective of the lower part of thecoupling.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a simple and durable shaft orpole coupling for vehicles.

The invention consists in combining with the cushion of a chill-couplinga box having a recess and back piece, a separate axle-clip, a screw threaded cap having ears that clasp the box, cut-away ears, and nut, ashereinafter fully described.

In the drawings, A represents the box or lower part of the coupling,held to the axle B by the clip 0, and projecting in front of the saidaxle B, as shown. The two sides of the box A have semicircular notches aa made in their upper edges, in which notches rests the bolt I), thatpasses through the eye I) of the shaft or pole E. In the front of thebox A is formed a rectangular socket or depression, 0, which supportsthe rear end of the shaft or pole E and prevents the lateral movementthereof. The cap or cover F of the box has a flat top, cut away so as toform rearward-projecting ears (I d, which clasp both sides of theupward-extending back piecefof the box; and this cover or cap F has alsotwo forward-projecting ears, 9 g, which assist in preventing I thelateral movement of the shaft or pole of the vehicle, and these ears 9 gare cut away on the under side, as shown at s, so that the said cover ortop F may fit more closely and securely in its seat on the box A.

Projecting downward at right angles from the cover F is its shank G,having vertical sides and back and a curved or recessed front, as shownat h, Fig. 1. This shank G is prolonged into a screw, which extends downthrough a hole, m, in the bottom of the box A, and on the end of thisscrew is turned the thumb-nut H, to hold the said cover F in place.andtop of the cover F is placed an elastic buifer or cushion, I, whichpresses upon the eye I) of the shaft or pole E when the said cover F isscrewed down into place. Attached to this thumb-nut H, and made a partof it, is the loop at, and the said thumbnut H is prevented fromaccidentally turning, and thus becoming loose, by the strap K, whose oneend is secured in the loop it, while the other end of said strap K isbuttoned 011 the button 0 and passed through theloop p of the plate L,which is fastened on the under side of the shaft or pole E.

It will be seen that by simply unscrewing the thumb-nut H the cover Fmay be readily lifted and the shaft or pole with its bolt be removedfrom the box; and it is obvious, also, that a shaft or pole may be heldfirmly in position by this coupling, and without rattlin g, thoughhaving sufficient play, when the elastic-lined cover is drawn tightlydown upon it.

Having thus described my intention, I claim as new and desire to secureby Letters Patent In a thill'coupling, the combination, with Within therecess formed by the shank the cushion I, of the box having rectangularrecess 0 and back piece, f, of the separate axleclip, the screw-shankedcap F G, having cars at g, and the not H, the ears 9 being cut away ate,as shown and described.
